Abstract
Abstract A security paper such as a bank note has a data matrix printed or attached to it. The data matrix includes an encoded unique identifier for the security paper which may be read by a scanner and compared with a store of unique identifiers to authenticate the bank note. The remote store may include an indication as to whether or not the bank note is activated or whether it has not been issued or has been released from circulation. Data on the data matrix may be arranged in layers with a second layer containing further data associated with the bank note. The data in one or more layers may be encrypted using different encryption algorithms whereby different parties may have access to the data on different layers. RFID tags may be used in addition or as an alternative to data matrixes.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
149 words
1 . A system for authentication of security papers comprising a repository of security paper related data, the store including, for each of a plurality of security papers, a token including a unique identifier of a security paper, and a status indicator indicating the status of the security paper; a generator for generating for a security paper a data carrier having encoded therein a token including a unique identifier from the store; a scanner for scanning the encoded data carrier to retrieve the unique identifier from the token; and an authenticator for comparing the unique identifier with stored identifiers and the status indicator corresponding to that unique identifier for authentication of the security paper, wherein the token comprises a header, a payload and a security portion, the payload comprising encrypted data relating to the security paper or a reference to a remote location at which that data is stored.
Claim 2
Dependent Claim
149 words
1 . A system for authentication of security papers comprising a repository of security paper related data, the store including, for each of a plurality of security papers, a token including a unique identifier of a security paper, and a status indicator indicating the status of the security paper; a generator for generating for a security paper a data carrier having encoded therein a token including a unique identifier from the store; a scanner for scanning the encoded data carrier to retrieve the unique identifier from the token; and an authenticator for comparing the unique identifier with stored identifiers and the status indicator corresponding to that unique identifier for authentication of the security paper, wherein the token comprises a header, a payload and a security portion, the payload comprising encrypted data relating to the security paper or a reference to a remote location at which that data is stored.
